In the batman-adv module (which implements a routing protocol for mesh netw=
orks
on layer 2) we are trying to switch metric from packet loss to throughput a=
nd
the idea is to read the estimation from the rate control component (thanks =
to
the API mechanism in cfg/mac80211 this can be eventually changed later).

I am not entirely sure that the value I proposed to read (the maximum in the
rate table) is the one which better plays the needed role. But the prelimin=
ar
tests demonstrated that it  :)


Cheers,
